Make sure you use the correct Drupal version

Your question doesn't specify which version of Drupal you're using. That table was available in D6, as confirmed in the module's installation process for the 6.x-2.x version of it. But that table is no longer available in D7, as confirmed also in the module's installation process for the 7.x-2.x version of it.

Re-install the module

Try a disable/uninstall of the og module, then re-install the module.

Sometimes it helps to restore and/or repair these kinds of problems.

Increase memory limit

Another option might be that you need to increase the memory size of your Drupal site. And then retry uninstall/reinstall one more time. Because each time you install a module, your site will be using more memory. So at some point (if you never increase the memory), you'll hit your available memory limit.

Assuming this is NOT a multi site, consider editing your /sites/default/settings.php, and change the line to set the memory limit. If it is a multi site, then edit the settings.php file related to the site where you are experiencing the problem.

That line in settings.php should look similar to this:

`ini_set('memory_limit', '128M');`

The '128M' in it might be some other number. Whatever the number is, try to increase it with like 50%, or maybe even double it to see what happens after you do so (of course do not forget to save the file after increasing that number).

Be aware also that the amount of memory you'll actually need, somehow depends on the number of enabled modules (the more modules you (try to) enable, the more memory you'll need.

If needed, refer to https://www.drupal.org/node/207036 for more details, eg if such 'ini_set' is not yet included in your settings.php file. As mentioned in that link: "Locate the PHP settings section and add that line at the end of that section".

Check logfiles

If none of the above helps, then check your log files (both Drupla logs and/or server logs) to find some kind of indication of possible errors.

Make sure you use the correct Drupal version

The initial version of your question didn't specify which version of Drupal you're using. Though the names of the tables you mentioned are from D7 (not used in D6). 

That table was available in D6, as confirmed in the module's installation process for the 6.x-2.x version of it. But that table is no longer available in D7, as confirmed also in the module's installation process for the 7.x-2.x version of it.
